FASTENER.

Application filed J une 25, 1917.

To all whom t may concern.'

Be it known that I, Louis ARKIN, a citizen of the United States ofAmerica, and resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Fasteners,of which the following is a specification.

This invention relates t0 separable fasteners of the type shown inLetters Patent of the United States N o. 1,225,741, granted to mev onMay 15, 1917, comprising essentlally complemental stud and socketmembers, the latter provided with stud-retaining and releasing means anda resilient member adapted to force the stud from the socket withoutmanipulation of said stud.

More particularly my invention relates to the stud-retaining andreleasingr means with which the socket is provided, and its principalobject is to provide stud-retaining and releasing means whereby the studWhile securely held within the socket is readily released to permit theresilient member provided for that purpose to force it from the socket,said stud-retainingand releasing means being so organized and arrangedthat the socket member shall have the thinness which is commerciallyessential.

Referring to the drawings which illustratean embodiment of myinvention,-

Figure 1 is a top view of the socket partially broken away;

Fig. 2 is a section on the line 2-2, Fig. l, the stud member being shownin elevation disengaged from the socket;

Fig. 3 is a side view of the socket;

Fig. 4 is a section on line 4 4, Fig. 2;

Fig. 5 is a view similar to Fig. 2, but showing the stud within thesocket.

A is a metal casing of usual contour having a stud-receiving aperture a,(Fig. 2) preferably of slightly greater diameter than the shank of thestud S so that the said stud while free to move into and out of thecasing is held against substantial lateral or tipping movement withinsaid aperture a. Within said casing is a pair of stud-retaining plates Blocated and movable in the same plane, pressed together and yieldinglyheld in normal position by one or more springs C (Fig. 4) which engagelugs B provided on said plates. Each of said retaining plates has anotched, hook-like end B2 whereby said plates are interlocked. Said endsengage each other when the plates are in normal position, as best shownin Fig.

4, the notches forming a stud aperture D located in the path of the studand into which it is adapted to enter upon its insertion into the casingA.

Each of said hook-like ends B2 is further provided with a guide E andthe body portions of the plates have complemental guide channels F, theguide E of one plate extending into the complemental guide channel F ofthe other plate to insure the movement of said plates in the same line.

B3 are the `stud releasers preferably formed integral with the plates Band extending outside said casing through slots in the wall thereof.Preferably the releasers are of the form shown having stops adapted toengage the wall of the casing when said releasers are pressed inward torelease the stud as presently to be described.

)Within the casing A and above said plates B is a resilient member G,preferably a spring plate best shown in Figs. 1 and 5, located in thepath of the stud S and adapted to be engaged by the stud upon itsinsertion into the casing and to be stressed thereby.

Between said spring G and said plate B is a stud-holding plate H havingan aperture 7L (Fig. 2) into which the stud ts upon its insertion intothe casing to anchor said stud and hold it against tipping.

The stud S is of the form shown having an enlarged head S preferablyflattened at the portion s which fits within the aperture L of theholding plate H. )V hen the stud S is inserted into the casing A throughthe aperture a, its head, entering the aperture D formed by the notchedretaining plates B, forces said plates apart and passes between theminto and partially through the holding plate H lifting the springG. Whenthe stud head has thus passed therebetween, the plates B close aroundthe neck of the stud, and said stud is thus firmly retained within thecasing with the spring G stressed thereby.

To release the stud, the releasers B3 are simultaneously pressed inwardwhereupon the hook-like ends B2 of the plates B are opened, releasingthe stud so that its head is free to pass between said plates and thespring G being thus released, jumps or forces the stud free of thesocket.

A socket member constructed in accordance with my invention as abovedescribed is not only simple and strong but by reason of the t'aet thatthe stud-retaining plates with their guides are located and niorable inthe sanne plane, can he made 'very thin. This feature is of priineimportance in all -fasteners adapted and intended for use upon clothing;for when the fastener is employed upon dresses and the like it isessential that it he as thin as'possible so as to be readily concealedfrom View. T he provision of thin st11d-retaining ineans o' especialimportance in this particular type ot fasteners; for the resilientineinher Whieh juinps or forces the stud frein the socket ot necessityoeeupies a relativelr'large space Within the easing; and the economy ofspace i'ieeessarjv to essential thinness niust therefore he ohtained inthe organization and arrangement ot the retaining,` and releasing`means.'
